The item in my kit
I bought BISOTHAI White D-Profile Seal Strip as part of my camper van equipment.
Fitting the custom cover highlighted the gaps created by angled panels and adjoining surfaces. This D-profile strip is part of the sealing and trim materials I purchased for the build.
Where it fits my build
I made a front panel and two triangular side pieces from black aluminum composite sheet. The cover let me orient the heater vent toward the van interior instead of following the sloping back of the seat platform.
I joined the panels with brackets and self-tapping screws, then fitted the assembly at the seat base. The angle of the platform made drilling awkward, and one screw position left a hole that I planned to cover with a larger washer.

My build notes
I liked the black composite sheet: it was easy to work with and cut, and I liked how it looked. The difficulty came at the angled fastening positions, where access mattered as much as the shape of the cut panels.
The finished panel shape and the access for fastening it had to work together.
Alternative products
Two alternatives to compare
Frost King's D-section strip offers a similar hollow-profile approach. Its vinyl-foam tape uses a rectangular foam section instead, changing the contact surface and compression shape.
Frost King D-Section Weatherseal
This Frost King strip uses a hollow D-shaped rubber section. The adhesive backing attaches the compressible profile along a closing edge.
